Could not load file or assembly 'Microsoft.AspNetCore.Connections.Abstractions' on ASP.NET Core only on Windows PC

This ASP.NET Core 2.1 Project runs fine on my Mac OS. However it throws this exception when I run it from Windows PC. I tried to run this from two Windows machines using the same version of .NET Core SDK.

I tried reinstalling .NET Core SDK 2.1.302, also tried upgrading to 2.1.401. Appreciate any help.

The error is

System.IO.FileLoadException: Could not load file or assembly 'Microsoft.AspNetCore.Connections.Abstractions, Version=2.1.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Used Nuget Packages in .csproj file

<PackageReference Include="HangFire" Version="1.6.19" />
<PackageReference Include="Hangfire.LiteDB" Version="0.1.0" />
<PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.3.0" />
<PackageReference Include="Microsoft.AspNetCore.SignalR" Version="1.0.1" />
<PackageReference Include="Microsoft.AspNetCore.WebSockets" Version="2.1.1" />

This problem is a known issue in .NET Core 2.1.x that was fixed in .NET Core 2.1.5 and newer. See https://github.com/dotnet/core-setup/issues/4512.

If you are getting failures due to "System.IO.FileLoadException" after updating the .NET Core SDK, you are probably running into https://github.com/dotnet/core-setup/issues/4376.

The best fix is to upgrade to .NET Core 2.1.5 or newer.

If you can't upgrade, another workaround is to update the project to

<PackageReference Include="Microsoft.AspNetCore.All" Version="2.1.3" />

The cause of this issue, as described in https://github.com/dotnet/core-setup/issues/4376, is unintentionally upgrading out of the shared framework. For example:

<PackageReference Include="Microsoft.AspNetCore.All" Version="2.1.0" />
<PackageReference Include="Microsoft.AspNetCore.SignalR" Version="1.0.1" />

Microsoft.AspNetCore.All 2.1.0 depends on Microsoft.AspNetCore.SignalR 1.0.0, but your project has upgrade to Microsoft.AspNetCore.SignalR 1.0.1. When you dotnet publish, you get Microsoft.AspNetCore.SignalR 1.0.1 AND ⚠️ its transitive dependencies in your publish folder. This is the publish trimming pitfall described in https://natemcmaster.com/blog/2018/08/29/netcore-primitives-2/.

This results in the following

+=================+===============================+================================+============================+
| AspNetCore.All  |  M.A.Connections.Abstractions |  M.A.Connections.Abstractions  |  Which M.A.C.Abstractions  |
|                 |  (in shared framework)        | (in publish dir)               |  should load               |
+=================+===============================+================================+============================+
| 2.1.0           |  2.1.0                        |  2.1.1                         |  publish dir               |
+-----------------+-------------------------------+--------------------------------+----------------------------+
| 2.1.3           |  2.1.3                        |  2.1.1                         |  shared framework*         |
+-----------------+-------------------------------+--------------------------------+----------------------------+

* This is bug, and https://github.com/dotnet/core-setup/issues/4512 tracks getting a fix in a future 2.1.x update.

If you don't have Microsoft.AspNetCore.All, you can use Microsoft.AspNetCore.App and set its version to 2.1.3. They are quite the same:

<PackageReference Include="Microsoft.AspNetCore.App" Version="2.1.3"/>

I solved the problem by upgrading Microsoft.AspNetCore.All from 2.1.0 -> 2.1.3 (upgraded SDK to 2.1.401)

Still don't have a clue why this was working on Mac but not on Windows.

My Web API Core project file didn't contain Microsoft.AspNetCore.All. I manually added it to the item group and it fixed it for me.
